A Simple Rest Library for android

This library is a simple Rest Service library that consume rest api written in Java for android

SDK Requiremnet

minSdkVersion >= 15 (Android 4 and above )

Importing to project

Example for Gradle:

Step 1. Add it in your root build.gradle at the end of repositories:

allprojects {
 repositories {
  ...
  maven { url "https://jitpack.io" }
  maven { url "https://maven.google.com" }
 }
}
If you're using gradle 3.+.+
allprojects {
 repositories {
  ...
  maven { url "https://jitpack.io" }
  google()

}

Step 2. Add the dependency

implementation 'com.github.Johnyoat:rest-service-lib:0.4'
implementation 'com.google.code.gson:gson:2.8.5'

Set 3. Enable Internet Permission

eg MainActivity.java

public class MainActivity extends AppCompatActivity implements RestService.CallBack {

    private TextView restData;
    private RestService restService;
    private ProgressDialog dialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        restData = findViewById(R.id.restData);
        dialog = new ProgressDialog(this);

        dialog.setMessage("Fetching Data...");
        dialog.setCancelable(false);

        Button fetchBtn = findViewById(R.id.fetchBtn);

        //Rest Url
        final String restUrl = "https://jsonplaceholder.typicode.com/posts";

        //Setting up Library
//        final RestService restService = new RestService(this);

        //Executing call,Note it's Async call
//        RestService restService = new RestService(this);

        fetchBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Setting Up Rest Service
                restService = new RestService(MainActivity.this);
                //Executing call,Note it's Async call
                restService.execute(restUrl);
                dialog.show();

            }
        });

    }

    //Response from the server
    @Override
    public void onResult(String response, String apiType) {
        if (response != null) {
            dialog.dismiss();
            restData.setText(response);
        } else {
            dialog.dismiss();
            Toast.makeText(this, "Check Network Connectivity", Toast.LENGTH_SHORT).show();
        }
    }
}

Adding Headers (Optional)

HashMap<String,String> headers = new HashMap<>();
// headers.put("HeaderName","Value");
headers.put("origin","*")
restService.setHeaders(headers);

Get Method

restService.execute(restUrl);

Serializing

You can use any json serializing libray but I'll use GSON in this example

Object obj = new Object();
String json = new Gson().toJson(obj);

Post

restService.execute(restUrl,json,"post");

Put

restService.execute(restUrl,json,"put");
